Dahlia plant named ‘Fidahnewy’

ABSTRACT

A new and distinct cultivar of  Dahlia  plant named ‘Fidahnewy’, characterized by its compact, upright, somewhat outwardly spreading and mounded plant habit; freely branching growth habit; freely flowering habit; large decorative inflorescences with light red purple-colored ray florets; and good postproduction longevity.

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘FIDAHNEWY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahliaplant, botanically known as Dahlia hybrida, and hereinafter referred toby the name ‘Fidahnewy’.

The new Dahlia plant is a product of a planned breeding programconducted by the Inventor in Hillegom, The Netherlands. The objective ofthe breeding program is to create new pot-type Dahlia cultivars thathave a freely branching and flowering habit, attractive ray floretcoloration and good postproduction longevity.

The new Dahlia plant originated from an open-pollination in Hillegom,The Netherlands of an unnamed selection of Dahlia hybrida, not patented,as the female, or seed, parent with an unknown selection of Dahliahybrida as the male, or pollen, parent. The new Dahlia was discoveredand selected by the Inventor as a single flowering plant from within theprogeny of the stated open-pollination in a controlled environment inHillegom, The Netherlands.

Asexual reproduction of the new Dahlia plant by cuttings in a controlledenvironment in Hillegom, The Netherlands since 2006, has shown that theunique features of this new Dahlia plant are stable and reproduced trueto type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensity,without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Fidahnewy’ . These characteristics incombination distinguish ‘Fidahnewy’ as a new and distinct cultivar ofDahlia:

-   -   1. Compact, upright, somewhat outwardly spreading and mounded        plant habit.    -   2. Freely branching growth habit.    -   3. Freely flowering habit.    -   4. Decorative inflorescences with light red purple-colored ray        florets.    -   5. Good postproduction longevity.

Compared to plants of the female parent selection, plants of the newDahlia differ primarily in ray floret coloration and plant shape.

Plants of the new Dahlia can be compared to plants of Dahlia hybrida‘Lisa Dark Pink’, disclosed in U.S. Plant Pat. No. 11,780. Inside-by-side comparisons conducted in De Lier, The Netherlands, plantsof the new Dahlia differed from plants of ‘Lisa Dark Pink’ primarily inray floret color as plants of ‘Lisa Dark Pink’ had dark pink-colored rayflorets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of thenew Dahlia plant. The photograph shows the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Dahlia plant. The photograph comprises a sideperspective view of a typical flowering plant of ‘Fidahnewy’ grown in acontainer.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and the following observations andmeasurements describe plants grown in a glass-covered greenhouse in DeLier, The Netherlands during the late summer and autumn and underconditions and practices which approximate those generally used incommercial Dahlia production. During the production of the plants, dayand night temperatures averaged 18° C. Measurements and numerical valuesrepresent averages for typical flowering plants. Plants were about 10weeks old when the photograph and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, Fifth Edition, except where generalterms of ordinary dictionary significance are used.
